Fused Silica Windows

13 Sep 2021

UVFS has excellent optical qualities. Product characteristics include extraordinarily low refractive index variations leading to state-of-the-art homogeneity values, low birefringence values, large size capabilities, exceptional transmittance from the deep ultraviolet through the infrared region, and an ultra-low thermal expansion coefficient; all of which are critical to our customers’demanding needs.

  UV Grade Fused Silica is synthetic amorphous silicon dioxide of extremely high purity providing maximum transmission from 195 to 2100 nm. This non-crystalline, colorless silica glass combines a very low thermal expansion coefficient with good optical qualities, and excellent transmittance in the ultraviolet region. Transmission and homogeneity exceed those of crystalline quartz without the problems of orientation and temperature instability inherent in the crystalline form. It will not fluoresce under UV light and is resistant to radiation. For high-energy applications, the extreme purity of fused silica eliminates microscopic defect sites that could lead to laser damage.Yutai Optics offers Chinese fused silica JGS1,JGS2,JGS3, as well as import Corning 7980,7979,8655.
